Answer:
x = 45 degrees +180 n where n is an integer
Step-by-step explanation:
tan(x)-cos^2(x)=sin^2(x)
Add cos^2(x) to each side
tan(x)-cos^2(x)+ cos^2(x)=sin^2(x)+ cos^2(x)
tan(x)=sin^2(x)+ cos^2(x)
We know that sin^2(x)+ cos^2(x) = 1
tan (x) =1
Take the inverse tan of each side
tan ^-1 ( tan x) = tan ^-1 (1)
x = 45 degrees +180 n where n is an integer
